German textile company Baur Vliesstoffe has developed a “natural, renewable and sustainable alternative to polyester fillings” made with virgin wool and corn.

Called lavalan, the wool insulation is said to already be used in outdoor brands including Fjällräven, Alpina Sports, Tatonka, Grüezi Bag and Ziener. The wool is said to be sourced entirely from European countries and to be mulesing-free.
